Take a picture of the plate for me so I can try to tell you what is going on there. I'll take a look in my book for you if you do. Vince

Here it is.....

Just to give you the heads up. That is a very old trans go kit. There are plugs that they have you install that I have never seen nor installed! The later kits do not install that many plugs. However they do have you drilling a bunch of holes in the valve body casting. I will look and see if I can tell you what the passage oil does. I will try to get back to you later today when I have time. It might be a good idea to think about starting over. The reason I say this is because with all the plugs that they have you install, I would be worried about having a possible cross leak. I will have to get back to you on this later. Vince

EDIT!!!! I forgot how involved that kit is with the seperator plate holes being filled in with the slugs! I actually have a valve body here on one a did a few years ago. It does have all the plugs. Let me take a look at what we have between the two of us and I will get back with you on some more info. Vince

On the valve body side my book is calling that passage orificed exhaust oil. On the case side the circuit is 3rd gear feed. So with that being said if you do not have the gaskets cut out as you were told then circuit can not be completed. I think if your clutches in the direct are ok, with doing this it should work. Hope this helps. Vince

thanks Vince....after spending a couple hrs looking at this I came up with the same results as you.
Im crossing my fingers that installing the gaskets with these holes punched out I will regain 3rd and also my reverse seeing reverse cannot happen unless the direct clutches are applies.

I figured it was an old kit caused the instructions say 1995

Thanks once again...I will post results when I reinstall VB
